SPECIFICATION formingpart of Letters Patent N0. 311,903, dated February10, 1885.

Application filed June Q, i894. (No model.)

To all whom it may concern.-

Be it known that I, WILLIAM R. Looms, a citizen of the United States,residing at New Bichmond,in the county of Clermont and State of Ohio,have invented a certain new and Improved Convertible Harrow,Sled,andMarker, of which the following is a specification.

My invention relates to harrows formed of two sections coupled togetherin such manner that the sections may be turned from a horizontalposition to vertical positions and connected together in parallel planesto convert the harrow into a sled or marker.

The object of my invention is, mainly,to probeams carrying teetharranged as in adouble- A-shaped harrow, one to follow the other, and toadapt this form of a harrow to be readily converted into a sled ormarker, as hereinafter described.

In the accompanying drawings, Figure lis a perspective view of theimplement when ready for use asaharrow; Fig. 2, a similar View of afragmentary part of theimplement, showing the forward ends of thesections spread apart for harrowing on both sides of a row of plants;and Fig. 3,aperspective View of theimplement arranged for use as a sledor marker.

'Ihe implement is made in two sections, A A', each of which are formedof two parallel beams, B C, of about equal length, secured together bycross-pieces D D, and are arranged in such manner that one end of eachof the beams will project beyond the corresponding end of the otherbeam. A metal plate, E, extends from the end of the forwardly-projectingbeam Bin a curved form around the inner side of therearwardly-projecting beam C, and forms a strong brace when used as-aharrow, and adurable runner when used as a sled. The sections A A arecoupled together at their for ward ends by a clevis, F, rings f f, andeyebolts f f', secured to the ends of the outer beams, B, and areconnected at their rear ends by an adjustable coupler-bar, G. The bar Gis formed in two parts, g g, each of which is hinged to a staple, g',secured to the rearcrosspiece, D, and are arranged to overlap each otherand be rmly bolted together by cranknuts and clamping-bolts g2, whichare tted in holes or slots in the overlapping ends of the parts g, bywhich means asure and convenient adjustment is secured. The location ofthe staples gupon the upper side ofthe cross-pieces D and their hingedconnection to bar G will admit` of the main sections A A being swungoutinto avertical position to convert the har'- row into a sled, or viceversa,without removing the bar G from its connections. Handles H,provided with squared shanks h h at their lower ends, are fitted snuglyin corresponding socket-plates, h h2, secured upon the adjacent sidesand rear ends of the rearwardly-'projecting beams C, and said handlesmay be interchangeablyplaced in either ofthe socket-plates to adapt thehandles to be used upon the sections when arranged either asa harrow oras a sled and marker.. A small pin orkey, h3, may be employed to securethe handles iin their sockets. The beams B and O are both provided withbarrow-teeth arranged in parallel converging rows arranged to followeach other, and the cross-pieces D may be similarly provided with teeth,to provide ample means for thoroughly breaking up and pulverizng thesoil.

Vlien the harrow is to be converted into a sled and marker the clevis Fis removed, the handles are transferred to the position parallel witheachother, a cross-brace, I, is then secured by bolts and crank-nuts t'rto the upper and forwardly-projecting ends of the beams B, and thetransformation to a sled and marker is completed.

Bolt-holes t' in the ends of the brace I and similar holes in theoverlapping ends of the bar-f G permit the adjustment of the runnerstoward or from each other to be regulated by or conform to the width ofthe row to be marked.

The cross-brace I may be provided with a hook, I, to connect it with thedraft attachments,and hooks I2 may be employed. to form corner-bracesbetween the barIand the beams B. When the sections A A are placed inposition to form a harrow, the bar I is disconnected at one end, swungaround upon the other locking-bolt, and placed in position closelyagainst the outer side of one of the beams B, and securely bolted inthat position to be conveniently carried and always ready for use. rlheprojection of the forward ends of the beams B above and beyond thecorreroo y sponding ends-of the beams C allows the sections A A to becoupled together in a double- Ashaped form, as shown in Fig. 1, so thatwhile their extreme forwardends are secured together by the clevis F theforward rounded ends Ofof the beams() may abut against each other tosteady the structure and form a shoulder-bearing or fulcrum-point fortightening the sections A A by means of the adjustable bar G, abovedescribed. The forwardly-projecting upper beam, B, when used as a sled,provides convenientrmeaus for `connecting the draft attachments, andenables the runners to ride freely over obstacles, and the rearwardlyprojecting beams G provide suitable and convenientzmeans for connectingthe handles to the sections when used in either-position.

When the forward ends of the sections AA i are coupled together by arigid link,/F, as shown'in Fig; 3, and the rear ends of said sectionsare properly adjusted by means of the bar G,the barrow maybe used tostraddle arow f vegetation,l and vany required adjustment may be made tosuit the spaces between the rows or adapt the implement to the characterof thelsoil Yor theI nature of the work. handles permit the sled orbarrow to be guided and directed in its course, to avoid obstacles,

\ and be held in the path of the team.

I am aware thatconvertible harrows and sleds or markers have heretoforebeen employed, and that combined harrows and sleds have been constructedwith beams which projectforwardly and rearwardly ot' each other.

The

I claim as my invention and desire to secure by Letters Iatent-V l. Theconvertibleharrow, sled, and marker composed of two frame-sectionsformed of parallel beams B C, united by ycross-pieces D D, and shod withthe forwardly-curved plate E, which 4serves both as a fulcrum Vandrunner, and provides an intermediate bearing-shoulder, C, incombinationwith'adjustable linked' either in the form of a double-Aharrow or 4a f sled and marker,the removable handles H,and sockets h h2,arranged, respectively, upon the adjacent sides` of therearwardly-projecting ends ofthe beams C, substantially as de scribed.

Y In testimony whereof I have hereunto subscribed my name.
